Focusing Technology ICP-5000 Inductively Coupled Plasma Emission Spectrometer is a full spectrum direct reading inductively coupled plasma emission spectrometer that integrates a two-dimensional spectroscopic system with a concentrated step grating, a self-excited all solid state RF power supply, and a research grade high-speed CCD. It can simultaneously analyze up to 72 elements, covering the vast majority of metal and non-metal elements in the periodic table; The detection capability reaches ppb level, which can directly determine the content of 9 impurity metal elements in ferrous oxalate, improve the quality of electrode anode materials, and enhance the economic benefits for lithium battery manufacturers!
